7871247 High modulus metallic component for high vibratory operation January 18, 2011
A high modulus component, such as an aircraft engine turbine blade, is formed from a base metal that has a high modulus crystallographic orientation that is aligned with the primary, i.e. radial, direction of the turbine blade. The base metal is Ni, Fe, Ti, Co, Al, Nb, or Mo based al
7704332 Moderate density, low density, and extremely low density single crystal alloys for high AN.sup.2 April 27, 2010
A single crystal alloy for high AN.sup.2 applications has a composition consisting essentially of from 4.0 to 10 wt % chromium, from 1.0 to 2.5 wt % molybdenum, up to 5.0 wt % tungsten, from 3.0 to 8.0 wt % tantalum, from 5.5 to 6.25 wt % aluminum, from 6.0 to 17 wt % cobalt, up to 0.2 w
7338259 High modulus metallic component for high vibratory operation March 4, 2008
A high modulus component, such as an aircraft engine turbine blade, is formed from a base metal that has a high modulus crystallographic orientation that is aligned with the primary, i.e. radial, direction of the turbine blade. The base metal is Ni, Fe, Ti, Co, Al, Nb, or Mo based al
6805750 Surface preparation process for deposition of ceramic coating October 19, 2004
A method of surface cleaning and controlled oxidation of superalloys is described. The method provides a thin homogeneous layer of relatively pure alpha alumina which is suited to receive and adhere to a subsequent vapor deposited coating.
6725540 Method for repairing turbine engine components April 27, 2004
The present invention relates to a method for repairing turbine engine components, such as vanes and blades, which have airfoils. The method broadly comprises removing oxidation debris from portions of the component by blending areas exhibiting thermal barrier coating spall and/or ox
6054096 Stable heat treatable nickel superalloy single crystal articles and compositions April 25, 2000
Improved compositions for fabricating nickel superalloy single crystal articles are described. The compositions are characterized by the substantial absence of carbon, boron, zirconium and vanadium and intentional additions of cobalt. The cobalt additions increase the stability of th
6007645 Advanced high strength, highly oxidation resistant single crystal superalloy compositions having December 28, 1999
A superalloy composition and single crystal articles of the composition are disclosed. The broad range, in weight percent, is 3.0-20.0% Co, 5.0-10.0% W, 5.0-7.0% Al, 0.4-2.9% Cr, 4.0-8.0% Ta, 0-1.0% V, 0-8.5% Re, 0-1.5% Ti, 0-3.0% Hf, 0-4.0% Mo, 0-2.0% Nb, 0-10.0% of one or more elements
5068084 Columnar grain superalloy articles November 26, 1991
An article exhibiting superior mechical properties and resistance to oxidation corrosion at elevated temperatures as described. The article has particular utility in gas turbine engines and is comprised of a nickel base superalloy consisting essentially of 3-10% Cr, 12.1-16% Co, 1.0-1.9%
4719080 Advanced high strength single crystal superalloy compositions January 12, 1988
A superalloy composition and single crystal articles of the composition are described. The broad range is 3-12% Cr, 0-3% Mo, 3-10% W, 0-5% Re, 6-12% Ta, 4-7% Al, 0-15% Co, 0-0.045% C, 0-0.02% B, 0-0.1% Zr, 0-0.8% Hf, 0-2% Nb, 0-1% V, 0-0.7% Ti, 0-10% (Ru+Rh+Pd+Os+Ir+Pt), balance essentia
4402772 Superalloy single crystal articles September 6, 1983
A specific composition range and process sequence are described for the production of single crystal superalloy articles which have an exceptional combination of high temperature mechanical properties and resistance to oxidation and hot corrosion. The nominal composition is 6% Ta, 9% Cr,
